 class SettableEdge
extends SimpleEdge

A utility class that allows the from and to nodes to be set separately. It is meant to be converted to a SimpleEdge after setting both ends.

IMPORTANT: this edge should not be added to a graph before setting both adjacent nodes (or better, it should always be converted through the toSimpleEdge() method).

Constructor Detail

SettableEdge

protected SettableEdge(java.lang.String label)

Constructs an Edge instance with the adjacent nodes not set.

Parameters:

label - : the label of the edge.

Method Detail

setFrom

protected SettableEdge setFrom(Node sourceNode)

Parameters:

sourceNode - : the source node.

Returns:

the instance itself.

setTo

protected SettableEdge setTo(Node destinationNode)

Parameters:

destinationNode - : the destination node.
